Implementations§

source§

impl<'a, 'b, 'tcx> PossibleBorrowerMap<'b, 'tcx>

source

pub fn new(cx: &'a LateContext<'tcx>, mir: &'b Body<'tcx>) -> Self

source

pub fn only_borrowers( &mut self, borrowers: &[Local], borrowed: Local, at: Location, ) -> bool

Returns true if the set of borrowers of borrowed living at at matches with borrowers.

source

pub fn bounded_borrowers( &mut self, below: &[Local], above: &[Local], borrowed: Local, at: Location, ) -> bool

Returns true if the set of borrowers of borrowed living at at includes at least below but no more than above.

source

pub fn local_is_alive_at(&mut self, local: Local, at: Location) -> bool

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
